ATTACHMENT F/OR CARTRIDGE-PRIMING; MACHINES.

SPECIFICATION forming part of Letters Patent N5. 479,819, dated August2, 1892.

Application filed March 24, 1892- Be it known that I, JOHN G. LIDDELL,of New Haven, in the county of New Haven, State of Connecticut, haveinvented certain new and useful Improvements in Attachments forCartridge-Priming Machines, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled inthe-art or science to which said invention appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification, in which- Figure 1 is a front elevation of myattachment; Fig. 2, an end elevation of the same, showing parts of theplunger and cartridgecarrier; Fig. 3, a perspective view of the racedetached; and Fig. 4, a like view of the top of the standard, showingrace-holder.

Like letters and figures of reference indicate corresponding parts inthe dilferent figures of the drawings.

My invention relates especially to an automatically-actuated attachmentfor delivering caps to the cartfidges in a position to be struck by theplunger; and it consists in certain novel features hereinafter fully setforth and claimed, the object being to produce a simpler, cheaper, andmore efiective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the plungerhead, which carries theordinary tool E, having a concave Working face and secured in thetool-socket b by a set-screw d in the usual manner.

B represents the ordinary rotary disk, which is provided with spindles0, arranged in the usual way and upon which the shells D are disposed.These parts being all of the ordinary construction, it is not deemedessential to herein specifically illustrate or describe the same.

A standard G is disposed near the disk B, and at an angle of aboutforty-five degrees to the line of travel of the plunger a raceway H ismounted. This raceway comprises two curved strips of metal h, (bestshown in Figs. 1 and 3,) on each side of which a rectangular Serial No.426,231. (No model.)

sheet of glass 1' is secured, the glass forming smooth walls for thepassage of the caps j, as hereinafter described. The lower glass platehas a steel backing k, and the longitudinal edges of said plates arebound at m. The converging ends of the race-bars h project inparallelism beyond the lower ends of the rectan-' gular plates, formingthe race proper p. The steel back is elongated centrallyunder the raceproper and thickened to engage the bars 71. and holdthe lower glassplate 1'. A cap-plate t in the plane of the upper glass covers the raceproper and is secured by screws 12, passing through the bars it into thethickened portion 60 of the steel back. Between the standard G and thedisk 13 a horizontal shaft J is mounted to rotate in standards w, saidshaft being slightly out of the plane of the race. The shaft J isprovided with conical sockets a: in its ends to receive the cone-shapedends of screws y, passing through the standards and forming bearings forsaid shaft. One end of the shaft is screw-threaded at 15. A pinion 16 ismounted looselyon saidshaftbetween tight-fittingwashers17.Jam-nuts18,turnedontosaidshafhre ulatethetensiononthepinion.Averticalrackbar F, secured to the plunger A, meshes with the pinion 16and reciprocates the shaft J as the plunger moves. A cap carrier K ismounted on the shaft and is constructed as follows: A block 25 is formedintegral with or attached in any suitable manner to the shaft, the upperface of said block being so arranged-that it may be thrown intoalignment with the bottom of the cap-racep. Pivoted on the block toswing horizontally in relation thereto there are two clamping-fingers26, the upper ends of which are grooved at 27, forming jaws to receivethe caps 3' when discharged from the race, as hereinafter described. Theblock 25 has a projection 28 on the shaft, the surface of which is inthe same plane as the upper face of the fingers 26 and which is disposedbelow their pivots. To each side of the projection 28 a flat spring 29is secured, the free ends of said springs bearing, respectively, on theouter edges of the clamping-fingers and tending to force them inwardlytoward each other. A stop-plate 30 is interposed between the fingersadjacent their pivots to prevent their free ends comng into contact. Aguide-plate 31 is bolted the block across said fingers.

On the top of the standard G there is a vocket 62 to receive the raceproper. This is ormed by a plate 61, secured by bolts 0" to he standard.In a suitable chamber or slot F2 in the standard G, at the mouth of the.ocket 62, a cut-off bar 33 is fitted to slide. iaid bar is 'providedwith inwardly-projectng arms 34, around which coiled springs Wedisposed, said springs acting expansively )etween the bar. and thechamber-bottom to ;hrow the cut-off across the mouth of the race groper,which registers with the mouth of the socket when in position.

The races II are detachable from the standtrds and the weight of thebody of the race is supported by brace-rdds 50, mounted in any suitableposition on the machine-frame. When a race is empty of caps, it can bewithirawn from socket 62 and substituted by one filled.

A spreading-screw 36, having a cone-shaped point, is mounted in thestandard G adjacent the cut-01f and in such position that it will beprojected between the fingers 26 to spread the same for receiving thecap.

In the use of my improvement the ordinary priming mechanism being inmotion and the plunger playing vertically as said plunger'descends, theparts being presumed to be in the position shown in Fig. 2, a cap fromthe race p is between the jaws 27 of the clamping-fingers, and therack-bar F, driven downward by the plunger, rotates the shaft J fromright to left, as viewed in said figure. The tension of the spring 29 onthe fingers as soon as said shaft starts and the fingers are out ofcontact with the spreader 36 causes them to grip the cap,which iscarried in the direction indicated by the dotted lines and arrow in Fig.2 and disposed directly over the cap-socket in the shell D. The partsare so timed that the cap arrives over said socket slightly in advanceof the working face of the tool E, which strikes said cap and drives itinto the shell in the ordinary manner. A stop 41, comprising a screwvertically adjustable in a standard 42, is disposed in such positionthat the face of the projection 28 on the shaft will engage it when thecap-carrier has described its arc and disposed the cap in position to bestruck by the plunger-tool, as specified. As the carrier is thusstopped, the pinion 16, stilldriven by the rack, slips on the shaft.Sufficient lost motion is thus afforded to enable the plunger to descendfar enough to strike the cap. As soon as the fingers of the cap-carriersleave the mouth of the cap-race the springs 35 throw the cut-ofi bar 34across the mouth of said race, preventing the caps from escapingtherefrom. Upon the return of the plunger the shaft is rotated in theopposite direction until the fingers engage the standards G at the mouthof the race, depressing the cut-off. The screw 36 spreads the fingers 26and admits a cap freed by the cut-off into the jaws 27. The

pinion 16 slips after the clamping-finger meets the standard during thecompletion of the upward movement of the plunger. The cap being driveninto the shell while held between the fingers 26, said fingers contactwith the tool E, and their jaws may be slightly beveled to enable themto slip readily over said tool on their return to the race.

Having thus explained my invention, What I claim is- 1.
